WASTE-PIPE PLUG.

Specification of Letters Patent.

Patented Apr. 20, 1915.

Application filed September 9, 1914. Serial No. 860,821.

' waste pipe plugs for use in connection with washbasins, washtubs,sinks, etc., and has for its object to dispense with the chains ingeneral use as well as to provide a more convenient plug.

The invention consists of the novel construction and arrangement of theparts and combination ofparts hereinafter more fully set forth in thefollowing specification and pointed out in detail in the appendedclaims.

In the accompanying drawings,Figure 1 is a side elevation with the plugseated. Fig. 2 is a vertical sectional view with the plug unseated. Fig.3 is a detail side elevation of the slotted seat. 'Fig. 4: is a planview of Fig. 1, the plug being removed.

Referring to the accompanying drawings, forming part of thisspecification, and in which like reference numerals designate like partsthroughout the several views thereof, 1 designates the discharge pipewhich is secured to the tub or basin (not shown) in the usual manner,and which is provided with the overflow apertures 2, 2 and thecrosspiece 3, which latter is provided with a screw-threaded aperture 4into which is screwed the tubular seat 5. 5 has a central apertureextending therethrough and a shoulder 6 which rests on the cross-piece3, and is also provided with slots 7, 7 on opposite sides thereofextending from the upper edge thereof down to said crosspiece 8. At itsupper end the discharge pipe 1 is provided with a ground seat 8 for theplug 9, which latter is also ground to fit said seat 8 and hasa stem 10projecting from its lower surface, the portion of said stem adjacent theplug 9 is flat, as at 11, for a short distance and adapted to operate upand down in the slots 7, 7, and to rest on the top of the seat 5 whenthe plug is unseated.

When the discharge pipe is closed the parts are in the position shown inFig. 1 of the drawing, and when it is desired to open the said dischargepipe to allow the water to flow from the tub or basin, the plug The saidseat 9 is' raised until the lower end of the flat portion 11 of the stempasses the upper edge of the seat 5 when the plug is turned to I allowthe said flat portion 11 to rest on the upper edge of the seat 5. Toclose the discharge pipe, the plug is turned until the flat portion 11of the stem comes in line with the slots 7 7 when the said plug willdrop and seat itself. It will be seen that the seat 5 is screwed intoposition in the cross piece 3 and is therefore removable at will.

' Having thus described my invention, what I claim is:

1. The combination of a discharge pipe having a cross-piece near itsupper end, and a seat removably secured to said cross-piece and havingslots in its opposite sides above said cross-piece, and a plug adaptedto seat in the upper end of said discharge pipe and having a stem on itslower surface having a portion thereof adapted to operate in said slotsand to rest on the upper edge of said seat to hold the plug in theunseated posi- .tion.

2. The combination of a discharge pipe having a cross-piece near itsupper end, and a slotted seat projecting above said crosspiece, andaplug adapted to seat in the upper end of said discharge pipe and havinga stem on its lower surface projecting through said seat and having aflat upper end adapted to operate in the slots of said seat and to reston the upper end of said seat to hold the plug in the unseated position.

7 3. The combination of a discharge pipe having a cross-piece near itsupper end provided with a screw-threaded aperture and a seat having ascrew-threaded lower end adapted to bescrewed into the aperture in saidcross-piece and having slots in its opposite sides above saidcross-piece, and a plug adapted to seat in the upper end of said discharge pipe and having a stem on its lower ,surface having a portionthereof adapted to operate in said slots and to rest on the upper edgeof said seat to hold the plug in the unseated position.

In testimony whereof I afliX my signature in presence of two witnesses.
